French Wikipedia
Mise-en-page is a term used to describe the physical layout of a page or a manuscript, features such as indentation, columns and spaces between paragraphs, but not the actual content of the page. It also encompasses other elements such as illustrations, pagination, margins, sidenotes and so on, as well as the choice of font or script and any decorative features. Mise-en-page is a French expression that translates as “putting on the page”.[1]
The related term mise-en-texte concerns the subdivisions of the text into chapters or scenes, and their subsections such as paragraphs or acts. From the 13th century onwards, different categories of books began to develop page layouts that reflected the requirements of their text or users. Even today, novels are conventionally presented in long lines of text, whereas dictionaries and other reference works have two or more columns to the page.[2]
